From the bus stop we proceed eastward along a path ascending moderately via Unterhauning and Gänsleit, leading us to the centre of Scheffau towards the village square near the church. We follow signs directing to Rehbachklamm. The trailhead is marked by a prominent stone sculpture, signaling the entrance to the gorge. Immediately before a bridge, the path to the Rehbachklamm branches off to the right. You cannot miss the entrance, a large stone sculpture points to it.

From now on the road becomes a little wilder. It gets narrower and stonier, goes up and down and again we change the stream side several times. Several wooden bridges cross the stream, some of them are only secured with a railing on one side, The path becomes somewhat rockier and more root come, then we reach a gravelled road and thus we have finished the first part of the Rehbachklamm.Under a wooden roof we enter the second part of the Rehbachklamm, the most spectacular one. Even a wire rope protection is attached to the rock. Under a wooden roof we enter the second part of the Rehbachklamm. A little further up there is already a suspension bridge, which we will reach right away. n next to a waterfall we go up a quite long wooden staircase, at the upper end of which gives a platform a good view of the waterfall. After a few meters we get uphill but first we reach an old mine tunnel. This one dates from the 16th. century and we can enter it a bit. At the entrance is a light switch, but with a headlamp you are definitely well equipped and can easily illuminate the studs. Beware with the head, the studs is quite low. In the tunnel you can see cuts from Aragonite, a Calcitart. After the mining tunnel, the next highlight of the upper gorge section follows immediately. A short but slightly swinging suspension bridge that spans a narrow gorge of the torrent. The path leads a short distance through the Rehbachklammum and with a few steps through the forest, then it ends at a wooden gate. Once you exit Rehbachklamm, you'll find signposts for various alpine routes. Look for the direction to Sonnenstein / Hintersteinersee.

The trail ascends first to the Hinterschießlingalm, a rustic alpine hut situated at approximately 1,020 meters elevation.

The first ~15–20 min are easy, gently climbing through mixed woods and clearings. After a while, the trail branches off steeper towards Sonnenstein. The trail becomes narrower and steeper, zigzagging through a beautiful pine and spruce forest. You’ll pass rocky outcrops and sometimes have partial views down towards Scheffau. We reach a beautiful waterfall coming down from the mountains. Great view of Wilder Kaiser accompany us! In front of us we have Sonnenstein, a striking rocky outcrop above the Kaiser Hochalm. Under the rock faces of the Sonnenstein the path climbs up on the south side to a small meadow ridge. From here you can reach the summit of the Sonnenstein quite quickly through the lashes. We descend on the east side on a narrow trail getting to Kaiser Hochalm.
